Take care when handling the HO2S and the O2S. Keep the in-line electrical connector and the louvered end free of grease, dirt, or other contaminants. Also avoid using cleaning solvents of any type. Do not drop the HO2S or the O2S. Do not roughly handle the HO2S or the O2S.Important: Bank 2 is the left bank.
Notice: Refer to Oxygen Sensor Notice in the Preface section.
Important: Removal of the oxygen sensor is easier when the engine temperature is above 48°C (120°F).
Installation Procedure
- Install the HO2S.
- Lower the vehicle.
- Install the HO2S electrical connector to the wiring harness bracket.
- Connect the HO2S electrical connector.
- Install the left side air inlet panel. Refer to Air Inlet Grille Panel Replacement in Body Front End.
Notice: Refer to Component Fastener Tightening Notice in the Preface section.
Notice: A special anti-seize compound is used on the oxygen sensor threads. New service sensors should already have the compound applied to the threads. Coat the threads of a reused sensor with anti-seize compound P/N 5613695 or equivalent.
